Single mom syndrome really has nothing to do with single moms themselves.

Single Mom syndrome is a form of entitlement expressed by able bodied individuals in the 1st world that can work, reason and be positive contributors but choose not to. They consume social media all day long, post pictures of their children, do drugs or drink alcohol and generally make excuses for why they can't elevate themselves out of their situations.

There may even be other mothers in the exact same situation, living at the poverty level with more children and worse conditions that do not exhibit this problem.
